  • When put on a drip for a patient, the power cord 51 is connected to the power supply to provide power for the temperature-controlled unit 3. Then, the adjusting current circuit 33 switches on, so that current flows through the heating member 31. Therefore, the heating member 31 becomes hot, that heats the perfusion tube and heating the transfusion liquid. According to the requirement of the patient, the hot value can be adjusted via slid the adjusting button 35.
  • In this invention, referring to FIGS. 1 to 7, the clamping member 1 includes a first holding body 11 and a second holding body 17. The first holding body 11 pivotably mounts to the second holding body 17, and can be rotated to move towards to or away from each other.
  • The first holding body 11 includes a mounting base 12, a securing plate 13, a cover plate 15, and a plurality of supporting panels 119. The mounting base 12 is similar to a case without a cover. Specifically, the mounting base 12 includes a side panel 114, two fixing panels 113 extending from opposites sides of the side panel 114, and two end panels 115. Each end panel 115 connects to a corresponding end of each fixing panel 113. The side panel 114, the fixing panels 113 and the ends panel 115 cooperatively define an accommodating space 116. An inner sidewall of the fixing panels 113 and the ends panel 115 extend a supporting block 117, used for positioning the securing plate 13. The side panel 114 defines a fixing hole (not show), for two power wires 7 pass through to connect to ends of the heating member 31.

  • Referring to FIGS. 2 and 3 again, during assembly of the clamping member 1, the first operation knob 112 and the second operation knob 173 are pivotably mounted together. The clipping protrusion 175 is engaged in the through groove 156, to form the through hole 10 with the flutes 155 and the fixing groove 118. The first operation knob 112 and the second operation knob 173 are urged or released to move away or towards clip the perfusion tube into the through hole 10. Specifically, referring to FIGS. 4 and 7, two opposite tabs 123 extend from the first operation knob 112, and two opposite tabs 178 also extend from the second operation knob 173. Each tab 123 and 175 defines a pivot hole (not labeled). The clamping member 1 further includes two fixing shafts (not labeled). Each fixing shaft passes through the pivot holes of one tab 123 and the corresponding tab 175, to mount the first holding body 11 and the second holding body 17 together.
  • In the other embodiment, each of the first operation knob 112 and the second operation knob 173 only has one tab, and the clamping member 1 includes one fixing shaft. The clamping member 1 further includes a torsion spring (also not labeled), to conveniently restore the first holding body 11 and the second holding body 17. Therefore, the fixing shaft passes through the pivot holes of tabs, with the torsion spring sleeved onto the fixing shaft, and two feet of the torsion spring respectively against the first operation knob 112 and the second operation knob 173.
  • Referring to FIG. 1, the temperature-controlled unit 3 further includes chassis 37, with the adjusting current circuit 33 accommodating therein. Obviously, the adjusting current circuit 33 is integrated in a circuit board, and the circuit board is fitted in the chassis, together with the adjusting current circuit 33. The chassis 37 defines a wire hole (not labeled) and a mounting hole (not labeled). Two power wires 7 together pass through the wire hole and the fixing hole of the side panel 114 of the clamping member 1, to connect opposite ends of the heating member 31 and the adjusting current circuit 33, respectively. The heating member 31 is in series with the adjusting current circuit 33. The adjusting button 35 mounts in the mounting hole, also in series with the adjusting current circuit 33. In Detail, referring to FIG. 9, the adjusting current circuit 33 includes a slide rheostat 331. The slide rheostat 331 is in series with the heating member 31. The adjusting button 35 is movably mounted to the slide rheostat 331. The adjusting button 35 is slid along the slide rheostat 331 to change the resistance value of the adjusting current circuit 33, so that the current flows through the beating member 13 is changed. Therefore, heat of the heating member 31 becomes changed.
  • The power adapter 5 includes a transformer and a booster, used for adjusting power voltage to supply voltage. In this embodiment, the transformer and booster adjust the power voltage to 12V, which is the proper voltage for the temperature-controlled unit 3.
  • Referring to FIGS. 1 to 3, by using the temperature-adjusted heater for transfusion, the power cord 51 is connected to the power supply, and then, the power adapter 5 provides a proper voltage for the temperature-controlled unit 3. Therefore, the adjusting current circuit 33 switches on, with the current flowing through the heating member 31 to generate heat. The first operation knob 112 and the second operation knob 173 are urged to move away to grasp the perfusion tube. When the perfusion tube is received into the through hole 10, the first operation knob 112 and the second operation knob 173 are released to move towards to fix the perfusion tube. Therefore, the perfusion tube is firmly against the heating member 31, and the transfusion liquid will become hot because of the heat of the heating member 31. According to requirement and feeling of the patient, the adjusting button 35 is conveniently operated to change the resistance value of the adjusting current circuit 33, so that the current flows through the beating member 13 is changed. Therefore, heat of the heating member 31 becomes changed and controlled, so that the temperature of the transfusion liquid substantially remains unchanged.
  • In the other embodiment, the clamping member 1 further includes a temperature sensor (not labeled) and a display (not labeled) electrically connected to the temperature sensor. The temperature sensor abuts against the transfusion tub, for detecting the temperature of the transfusion liquid flowing through the clamping member 1, which is shown in the display. Therefore, the patient or medical workers conveniently operate the adjusting button 35 according to the temperature shown in the display.
  • In the other embodiment, the chassis 37 and the adjusting current circuit 33 can be omitted, and the side panel 114 of the clamping member 1 defines an installing hole. The adjusting button 35 is mounted in the installing hole, and electrically connected to the heating member 31. Specifically, the adjusting button 35 is movably mounted to the heating member 31, and can be slid along the slide rheostat 331 to change the resistance value of the heating member 31. In this condition, the heating member 31, the adjusting button 35, and the power adapter 5 forms a circuit. The adjusting button 35 is slid to change the resistance value of the heating member 31, to change heat of the heating member 31. Therefore, the temperature of the transfusion liquid substantially can be adjusted.
  • Other applications, advantages, alternations, modifications, or equivalents to the disclosed embodiments are obvious to those skilled in the art.
